Major, what make/model is the pistol grip on your KM4-Tactical, and where did you get it?

jberkom: sorry i just got this grip from my buddy who got it from the philippines, so i don't know what brand is it because it didn't come in any packaging. although, it's quite similar if not the same as a g&p pistol grip- if that helps..

I have a quick question about the UTG rails you have because I am considering buying them for my m4 also.
Can you fit a battery in it? If, not can you mod a battery to fit in it? I tried to contact the UTG company by e-mail, but they kept sending me advertisements!
